[PATCH] D139852: [amdgpu] Lower CopyToReg into SGPR explicitly to avoid illegal vgpr to sgpr copy

[Jon Chesterfield via Phabricator via llvm-commits]

JonChesterfield added a comment.

Patch in D139874 <https://reviews.llvm.org/D139874> fixes up the invalid copy downstream but is likely to become more complicated than this in the process. One approach would be to land this and then, once D139874 <https://reviews.llvm.org/D139874> is completed and committed, delete this patch to ISel and update the test if necessary.
